Sandspiel vs SkyBound simulator

Sandspiel is a falling sand physics simulator. It is creative toy where players can place elements (like sand, water, fire, plants, etc.) and watch them interact according to simulated physics rules. The game lets you paint with elements and observe surprisingly complex chain reactions: water flows and pools, fire spreads and consumes, plants grow and creep, sand piles up. It's a sandbox for experimentation with no goals beyond play and discovery. Sandspiel embodies constructivist principles — giving you tools to explore and discover rather than explicit objectives to complete, and facilitates calm reflection and healing.

SkyBound is a serene flight simulator built for touch — tilt to fly, from takeoff to touchdown. FEATURES • Intuitive tilt controls with virtual throttle and rudder — airborne in under a minute • Lightweight flight physics: lift, stall, wind and thermals • Three handcrafted worlds: Azolla Islands, Sedona Canyon and Hydal Fjord • Four aircraft: trainer, seaplane, glider and jet • Ring-gate courses, cargo runs and landing challenges — earn stars to unlock new aircraft • Time-of-day presets: clear morning, golden hour, breeze, fog and night • Ride thermals in the glider and master crosswind landings
